Botanical Name

QUERCUS agrifolia

Plant Common Name

California Live Oak

General Description

The gnarled, picturesque trunks and aged branches of the California live oak have interesting evergreen, holly-like foliage. It naturally resides along the coasts and foothills from Central California southward into Mexico. Its bark is smooth and gray but becomes darker and mildly furrowed with great age.

The leathery dark green leaves of California oak are oval to elliptical in shape with spiny teeth along the edges. They are evergreen but shed in abundance in spring before quickly being replaced. As the new leaves open, the male flowers appear. These greenish pendent catkins spread copious amount of pollen and are directly followed by the female flowers, which are tiny, red and found at the base of the young leaves. The fruits are pointy light brown acorns that mature late in the season.

Plant California live oak in average, well-drained soil that is acid to slightly alkaline. It is important to refrain from overwatered or fertilizing established trees as this can cause stress and decline. In summer the roots should be kept dry but the trees may appreciate supplemental irrigation during unseasonably dry winters. Sadly, this species is susceptible to the sudden oak death, so keep an eye out for symptoms like bleeding cankers on the trunk and branch dieback.

This elegant, picturesque tree has been in the backdrops of many classic Hollywood movies. It adopts its best looks if planted in open, windy areas where it can become large and sprawl. It naturally branches low, so street tree specimens must be limbed up for safe vehicle and pedestrian passage.

California wildlife also appreciate this oak. The acorns are eaten by small animals, and the leaves are important food for the larvae of California sister and duskywing butterflies.

To distinguish this oak from the similar canyon live oak (Quercus chrysolepis), note that the canyon oak's leaves are slightly smaller and its acorns have fuzzy golden caps.
